Job Description

About us

We are the leading mobile point-of-sale (mPOS) company in Europe. Our company vision is to become the first ever global card acceptance brand. Today tens of thousands of merchants accept card payments with SumUp in 15 countries including Germany, the UK and Brazil.

Why work for us?

We do things differently. We build our own payment solution end-to-end so that we can always offer the best value & service. We know how vital payment is to small business, so we use our technology to solve their problems. We believe in open and transparent communication, not strict rules and hierarchies. If you’re looking for the chance to innovate, and disrupt the payment industry – join us.


We are looking for a Technical Integration Specialist who can master all the technical aspects of integrating SumUp's APIs and SDKs, while also translating those into the vernacular of people in sales, operations, or engineering. A successful candidate will be able to improvise and adapt to the needs and the technical requirements of the partner he or she is supporting.

Your work as a Technical Integration Specialist is ever-evolving. One day, you might help a long-time partner use our brand new Receipts API to customize the receipts their customers receive when they pay with SumUp behind the scenes. The next, you'll do some troubleshooting with a brand new partner and their engineering team until they successfully process their first transaction. After that, you might update the technical documentation to address common questions or challenges you notice integrators are having.

At its core, this is a technical position, so you should have an in-depth understanding of technical aspects of web, server-side, and mobile development.

SumUp's solution can get a new partner transacting in just a few hours, and you will be a key component in improving that process even further.


On a high level, you can expect to:

  • Work with 3rd party developers who are integrating SumUp’s API and SDK product
  • Provide technical support to internal Sales and Ops units as well as partners' engineering team
  • Take an active part in troubleshooting, testing, launch and post go-live monitoring integrated solutions
  • Help SumUp's Business Development team manage relationships with existing partners and sign up new integrators
  • Produce and maintain integration manuals, guidelines, and other technical documentation that improve the integration experience
  • Work with SumUp's Engineering and Product teams to address integration issues, improve existing integration products, and develop new ones


  • Obtained or are currently pursuing a degree in Business Informatics or an alternative discipline that comprises a good mix of business and IT
  • Knowledge of native mobile development
  • Past experience with or interest in the payments industry
  • Hands-on experience integrating 3rd party APIs, RESTful services, and native SDKs for Android/iOS/Windows
  • Ability to communicate effectively with both technical and non-technical individuals
  • A self-starter, motivated, innovative, and capable of quickly learning/adapting.
  • Fluent in English
  • When applying, please include a brief cover letter explaining your motivation for applying to this position


  • Flat hierarchies and the opportunity to have an impact, irrespective of your job description.
  • Convenient location in the heart of Mitte at U-Bahn Oranienburger Tor.
  • All the startup swag you expect: kicker table, table tennis, beer in the fridge, and more!
  • Our office has a strong sense of community; we get together regularly for brunches, cocktail nights, soccer, and yoga.
  • Our team comes from 24 different countries creating a fun, international environment.
